Question about Televison & Video

1 Answer

To further clarify my prior problem, the TV was plugged in, but powered off. I am assuming I need to power on before adjusting the voltage but I don't want to accidentally fry anything. General tips would be appreciated.

Hello,

your TV is having a power problem. The power supply board is defective that's why the TV won't power up. Its receiving power but it cannot transfer the current to the necessary part of the TV because a capacitor, diode, etc may have been faulty. Until these bad components are replaced, the TV might not come on.

If you know about TV repairers, I would suggest that you open the TV and read the power board/panel with a meter, detect the bad component and replace it. Take note that TV stores a lot of current that can shock, so leave the TV for a while before you open it.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you.

I wish you good luck.

SEIKI SE322FS LED TV won't turn on, but power light is on


From your description there are blown electrolytic capacitors on the power supply board,a visual inspection will show bulged burst or leaky caps.I am assuming there is no sound or pic and no visible light from the screen.I must assume you have no prior electrical service knowledge and warn of possible high voltages being present on the primary side of the power supply at the 400volt filter cap
also be sure to unplug the set before removing the back pannel

keep safe

Do you know how to use a meter? If so the first thing to do is take the back off and check the AC fuse, if this is blown replace it and see if the set works. If it blows again you have a short in the primary power supply and replacement of the power board will be required. If the ac fuse is good you will need to check all the plugs coming out of the power supply for voltage, if you have voltage coming out then you could have a bad main board or power supply. If you have no voltage coming out and the fuse is good then replacing the power supply is required. Let me know what you find and I can help you further!

Have you checked it using a different input device such as a DVD player? Have you ensured that the replacement board is exactly as per the original and the voltages at connectors are in same position and rating? If there is a voltage drop in any of the pins, look further in that direction and you can catch the culprit and conclude.

Ensure there is proper voltage on the power outlet. Try changing the TV to a different power outlet you are sure that works. Try changing the input device to something you are sure works. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

Dead set (no indication lights coming on when I push the power button.


Hi Gwendolyn,

First of all thank you for posting your question here at Fixya.
I'm assuming here that you're TV is a Vizio L32 HDTV.
My initial advice is to ensure that the AC source(outlet) is live. Please plug the unit to a known working outlet, if you are using a surge protector, directly plug the power cord of the TV to the outlet to confirm that the AC source is not the issue here.
If you've confirmed that the AC source is not the problem, then the fault is inside the TV and most likely the power supply. Most of the TV with a dead set symptoms that I've encountered is a power supply issue but of course needs to be confirm.

If your unit is not under warranty period (if so, avail it because the manufacturer will fix it for free, opening the rear cover will void the warranty), open the back cover, check the internal fuse of the power supply board, this is near where the AC power cord's directly connected. Check its continuity using the multimeter/ohmmeter, if you found it open, replaced it with a new same current rating that is printed on its body itself. Sometimes internal fuse fail due to voltage surge/flactuation, aging, etc, replacing with new one resolve the issue, however if the fuse blow again, this is an indication of more serious problem on the power supply board, it needs to replaced the entire board.
If the fuse is intact, you have to measure the output voltage of it through connector J1 (pin 9,10,11). You should be getting 5 Volts. If there's no voltage at these pin, you're power supply board is dead, replaced the entire board. If the 5 volts is present, replaced the main board.
I've provided you a links for the power supply board and mainboard below.

Rating and feedback are highly appreciated!

Hope I helped you.
Good luck and take care!
Have a nice day!

Tv won't turn on


I assume you do not have any red light showing on the front of the TV to indicate it is receiving power? Again assuming the your mains electric supply is functioning & the fuse in the TV plug is ok, if there are no signs of life & then most likely a fuse in the power supply may have blown. If you have a multimeter you could remove the rear of the TV & check the fuses in the power supply, if these are ok then you will need to check any supply voltages coming from the power board. If one of the fuses are open circuit, check some of the doides or transistors for any short circuits. If you are not comfortable doing this, then it would be advisible to contact a repair service centre.

Charger in not charging the battery


You can get an A/C adapter online on various websites or Ebay for around 20-30 dollars plus shipping. That should rule out whether the problem is your adapter or the laptop.
